I've got some questions about Sendmail. I know there is a ton of information out there, but I'm not too swift on the uptake, so if anyone can help me out, I'd appreciate it.

I have installed Slackware 9.1. I upgraded to -current via swaret. I made sure that /etc/rc.d/rc.sendmail is executable. I fire up Pine and start testing things out. I'm in a user account, so for "To:" I put "root". When I press enter, Pine completes the address as "root@slakbox.localhost". So far so good. I create a message and send it. I su and fire up Pine. Check my INBOX, and, sure enough, I got the message. I reply to the message, quit Pine, and logout. Now, as a user, I fire up Pine again, and there's my reply. Everything is looking golden.

Now, I decide to do a little more testing. Still in Pine as a user, I send a message to my hotmail account. Crank up the web browser, and sure enough, I got mail!!! Beautiful. Only thing is, the sender is shilo@slakbox.localhost. Not really a problem, since that's who sent it. Replying to that message, though, as I'm sure you have figured, doesn't do anything.

Now I have myself an account with dyndns.org. Makes it real easy to ssh over to my computer from work. I'm thinking, though, that there is a way to make it so my email address can be username@myaddress.dyndns.org. Am I thinking right here? That way, I have my own free email server. When I've messed around with Apache, I could easily set it up so that http://myaddress.dyndns.org would open up a web page I created on my computer.

What do I have to change to make it work the way I'm thinking? if my expalination isn't clear, let me know and I will try to re-phrase.

TIA,

Shilo

In order for you to receive mail to your current IP address from other e-mail servers(hotmail...) you would have to have a DNS entry somewhere that the e-mail server would be able to use to find the IP address of your mail server. This is called an MX record. Not sure if this is possible with a dynamic IP but hey dyndns.org might offer something like that.


Joe--

I believe they do. https://www.dyndns.org/support/kb/mxrecords.html . I'm just not too sharp on figuring this out. Anyone know what I'm talking about/trying to do here and can put it in layman's terms for me. I'd really appreciate it.

Thanks again,

Shilo

Anyway, I keep reading around and it turns out that this is all I have to do.

I've got myself an account with dyndns.org. I've got a router that supports updates to my account at dyndns.org. That means that if I want to find my computer, I just use myaddress.dyndns.org instead of an ip address. I've got Sendmail. All I had to do was:

1) Open up port 25 on my router. Of coarse, that meant forwarding it to my computer, but I figure that's a given.

2) Run netconfig. I changed my hostname to "username" (That's the same as I have it set up on dyndns.org) and I change my domain name to "dyndns.org".

3) Restart Sendmail.

BLAM, works like a charm.
